ubunut 10.04, does anybody know how i can turn my ubuntu laptop into a wifi hotspot?

Try this: http://www.howtoforge.com/wifi_hotspot_setup

The link in the previous reply has to do with using a Linksys Router.

Still looking for the actual answer to the original question.

...okay. I haven't done this for years, and it was with Slackware, but you'll need a wifi card that will go into "master" mode, hostapd, and probably to set up a bridge interface or do some iptables forwarding tricks.

For the first, run lspci and look for your wireless adapter's chipset number, and then go here:

...and see if there's a "yes" in the AP column. If not, you need a new wifi adapter.

After that, I'd look at this page. It's for Arch, but the basics will be the same for Ubuntu.

https://wiki.archlinux.org/index.php...e_Access_Point

From there everything should Just Work(tm).

Try this, it is for debian but should work with Ubuntu, too: http://agentoss.wordpress.com/2011/1...-debian-linux/

Funnily enough, I'm potentially going to want to do something along these lines with a Red Hat/CentOS/Scientific* laptop...

*Depending on what I choose to go with.

Use hostapd.
fisrt you need to put your eth0 to bridge
in hostapd you need to have line (preferably somewhere very close to top):
and then
then wait few seconds
No iptables, arptables, ebtables needed. It is just working
